IMPROVEMENT IN COMBlNED GRATES AND ASH-SIFTERS.

Specification forming part of Letters Patent No. 147,347, dated February10, 1874; application filed May 11, 1872.

Similar letters of reterence indicate corresponding parts.

My invention relates to a pivoted weighted grate or screen-plate and acoal and cinder pan, which is cut out on one side to adapt it to receiveand support the front end of the same, in combination with a stationarygrate, forming the bottom of a tire-pot, as herein described.

A in the drawing represents a fire-place grate of suitable style. Underit arranged a perforated plate or screen, B, which is pivoted andsupported on lugs to, that project from the legs or sides I) of thefireplace. The screen 13 is so pivoted,or so weighted at its front end,

that it will of itself maintain an inclined position, as shown in thedrawing. C is a pan, which is cut out on its inner side to adapt it toreceive and support the lower end of the screen 13. It is also providedwith projecting lugs cl, which will hold the screen inclined in case theweight of einders, &c., at its rear end should at any time overbalancethe front end. The pieces of coal or cinders falling from the grate Awill be conducted, by the screen 13, into the pan 0, while the ashesfall through the perforations of said screen, thus becoming separatedfrom the matter that may yet be used as fuel.

I do not claim the combination of an inclined screen with. a stationaryor other grate; but

I claim The combination, with the grate A, of the pivoted screen B,weighted, and projecting at its front end, and the pan 0, cut out on itsinnor side, as and for the purpose specified.
